IMPROVEMENT IN ORGAN COUPLERS.

Specification forming part of Letters Patent N0.'14S,685, dated March 17, `1874;

application filed January 24, 1874.

To all whom it may concern:

Be it known that I, CHARLES W. FossLER, of Adeline, in the county of Ogle and State of Illinois, have invented a new and Improved Organ Coupler, of which the following is a specification 'ln the accompanying drawing, Figure l represeuts a vertical section of our improved organ coupling device on the line cc, Fig. 2 5 and Fig. 2 is a top view of the same.

Similar letters of reference indicate corresponding parts.

The object of my invention is to produce an improved organ coupling device, which is simpler in construction, more easily worked, and less expensive than the couplers hitherto employed. My invention consists of a pivoted platform, to which the coupling-arms are attached, bent in such shape that, on throwing the platform up, the keys will come in contact with the arms when de-pressed, and thereby couple the corresponding pins to those originally depressed by the keys.

In the drawing, A represents the keys of an organ, which are made in the usual manner. B are the pins, which are depressed by the keys in playing the organ, passing through the perforated piece C, and returning into the former position by means of a spiral spring, a., acting on shoulder I1 of each pin. The plat. form Dis pivoted, either in front or rear of piece C, below the keys A, and provided with side anges d, ruiming along the full length of Y the platform. To these flanges d are pivoted the coupling-arms E, which are made of wire or other material of suitable strength. Arms E extend obliquely from one key to its upper or lower octave, and may be arranged so that three octaves-two in the treble, and one in the bass`inay be used. That part of each arm E immediately below the key is bent np- Aand easily ward, the end nearest to it being pivoted to the outer flange of the platform l), the end ot the oblique part passing through the opposite flange, and engaging the shoulders b oi' the pin to be coupled to the key, shown in Fig. 2.

The' raised part of arm E may be arranged -in either one ofthe two forms shown in Fig. 2,

by which a sufficient leverage to depress the pin and an easy movement is produced.

The platform I) is operated by a pivoted lever, D, which maybe thrown into either direction, or be connected to the`common stop or knee lever. B v raising lever 1) the platform I) is carried into an inclined position, so that the keys, when depressed, come in con tact with the upward-curved parts ol' arms l5, and, pressing thereon, cause their projecting ends to-work on the shoulders ol' the pins, and to sound thereby the octaves ot the keys originally touched.

lIhe construction of thearms, and their con neetion with the keys and pins, is very simple,

operated, so that hardly any repairs are required, and the whole coupling de vice may be furnished cheap, while working with the same eicacy as the more complicated and expensive coupler.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The im noved organ cou )ler consisting` of pivoted platform D, operated by lever D', and provided with flanges d and obliqnely-extending coupling-arms E, in combination with the keys A and pins B of aul organ, all constructed and arranged as set forth and shown.
